The semi-bridge sludge scraper is lightweight and economical, making it suitable for small to medium-sized circular sedimentation tanks. Its single-sided drive ensures reliable operation, and the scraper blades adhere closely to the tank bottom for thorough sludge collection, while also removing surface scum. The equipment is easy to install and operate, and is widely used in residential wastewater treatment plants, food processing plants, and aquaculture wastewater treatment, achieving stable sludge collection at low cost.

The Center Drive Sludge Scraper is the core sludge removal equipment for circular sedimentation tanks, thickeners, and clarifiers. The drive unit installed at the tank center rotates the truss structure, enabling the bottom scraper blades to gradually collect settled sludge into the central sludge hopper, while surface scum is collected by the skimmer into the scum trough. Our equipment features modular design, compact structure, smooth operation, and easy maintenance. Widely used in primary and secondary sedimentation tanks in municipal WWTPs, as well as sedimentation and thickening processes in industrial wastewater treatment.

• Center Drive Structure
  Drive Unit: Located at the tank center, consisting of gear motor, worm gear reducer, and slewing bearing, providing high torque transmission and smooth operation.
  Bridge: Hot-dip galvanized or stainless steel truss structure spanning the tank diameter, serving as an access walkway while supporting the drive unit.
  Scraper Arms: Symmetrically arranged arms connected to the center column, available in single-arm, double-arm, or multi-arm designs based on tank diameter.
• Adjustable Scraper Blades
  Scraper Blade Material: Standard rubber blades, wear-resistant and non-damaging to the tank bottom; optional stainless steel blades.
  Height Adjustable: Adjustable connection between blades and arms allows fine-tuning of blade height based on tank bottom flatness, ensuring effective sludge collection.
  Overload Protection: Blades automatically deflect when encountering hard objects, preventing equipment damage.
• Scum Removal System
  Skimmer: Installed on the scraper arms, rotates to collect surface scum to the tank periphery, guided by scum baffles to the scum hopper.
  Flushing Device: Optional water flushing pipe to periodically rinse the scum hopper, preventing clogging.
  Scum Baffle: Stainless steel baffle, effectively guiding scum into the scum trough.
